We're declaring it #RedSunday at Toyota Stadium and encouraging all fans to wear red to Sunday's match. No excuses, we need everyone in the stadium to be in their best FCD red to support the boys as we look to take down the #1 seed.

We beat them 3-1 just a month ago, and we're going to do it again. Toyota Stadium will be a sea of red on #RedSunday and we need everyone to do their part.

On Wednesday night, FC Dallas clinched their spot in the MLS Western Conference Semifinals with a 2-1 win over Vancouver Whitecaps FC in the wild card round match and with that brings a new playoff format.

Those of you who are UEFA Champions League die-hards will know exactly what a "two-legged aggregate" playoff means, but for those of who you follow FC Dallas either casually or fanatically, we're here to explain the ins and outs of the system.

Over the next week and a half, FC Dallas and Seattle Sounders FC will play twice, at Toyota Stadium on Sunday, November 2nd at 8:00PM and at CenturyLink Field in Seattle on Monday, November 10th at 9:30PM. The two games will be normal 90-minute MLS matches, but it's the combined score of the two matches that will determine who moves on to the Western Conference Finals. Let's go through a few scenarios:

FC Dallas wins the "first leg" in Frisco 2-0 and loses the "second leg" in Seattle 1-0. FCD would advance to the conference finals because the combined, aggregate score is 2-1 FC Dallas.

FC Dallas and Seattle Sounders FC draw 0-0 in the "first leg" in Frisco and Seattle wins 2-0 in the "second leg." Seattle would advance to the conference finals with a 2-0 aggregate win.

That make sense? Well let's talk about ties.

Away goals

Should FC Dallas and Seattle be tied in aggregate score after the games in Frisco and Seattle, one of two things will happen.

First off, let's talk about "away goals." Again, those of you who watch the UEFA Champions League are familiar with this rule and basically it means if the game is tied after 180 minutes, two games, whoever scored the most goals in the other team's house will advance to the conference finals. Again, let's go through a couple scenarios:

FC Dallas wins the "first leg" in Frisco 2-1 and loses the "second leg" in Seattle 1-0. Despite being tied 2-2 on aggregate, Seattle would advance to the conference finals because they have one "away goal" to FCD's zero.

FC Dallas and Seattle draw 1-1 in the "first leg" in Frisco and draw 2-2 in the "second leg" in Seattle. Despite being tied 3-3 on aggregate, FC Dallas would advance to the conference finals because they will have two "away goals" to Seattle's one.

Extra time and shootout

If the teams are tied after both games and also tied on away goals, the match will go to 30 minutes of extra time and if it is still tied, we will go to penalty kicks. You saw both of those scenarios in the Lamar Hunt US Open Cup semifinal against Philadelphia Union earlier this year. Away goals is not in effect once you get to overtime. Basically, if both games finish with the same score, we're going to overtime.

FC Dallas wins the "first leg" in Frisco 2-1 and Seattle wins the "second leg" in Seattle 2-1. The teams would go to 30 minutes of extra time after the second game in Seattle as the teams are tied on score and away goals. If neither team scores in overtime, it goes to penalty kicks.

FC Dallas wins the "first leg" in Frisco 3-1 and loses the "second leg" in Seattle 2-0. The Sounders would advance despite being tied 3-3 on aggregate as they lead 1-0 on away goals.

Does that all make sense? Score more goals than the other team over two games, you win. Score the same amount of goals and more goals in the other team's house, you win.

FC Dallas will host the first match of the series this Sunday, Nov. 2 before wrapping up the two-leg series in Seattle on Monday, Nov. 10. The winner will face the winner of the other semifinal between the LA Galaxy and Real Salt Lake in the Western Conference Championship.

FC Dallas edged out Vancouver Whitecaps FC 2-1 in the Western Conference Knockout Round of the 2014 MLS Cup Playoffs, presented by AT&T, Wednesday night. Dallas scored the first goal of the match when Mauro Diaz set up rookie forward Tesho Akindele for a goal in the 40th minute.

First Half Highlights

Vancouver equalized in the 64th minute on a goal by Erik Hurtado, but FCD would retake the lead 20 minutes later when Whitecaps center back Kendall Waston was called for a handball in the box. Michel converted from the spot to clinch the win for FC Dallas.

FC Dallas returns to the postseason for the first time since 2011 when the team hosts Vancouver Whitecaps FC at Toyota Stadium Wednesday night. Scott and Daniel get you ready for the start of FCD's playoff run with the Keys to the Match, driven by Toyota.

FC Dallas and Vancouver Whitecaps FC have played three hard-fought games in 2014 and they’re going to go at it one more time on Wednesday night in the 2014 MLS Cup Playoff curtain-raiser, a do-or-die wild card round matchup. Let’s take a look back at the three matches they’ve played this season:

Vancouver Whitecaps FC 2, FC Dallas 2 – Sunday, July 27th BC Place

Raul in Vancouver

Goals from Michel and Blas Perez saw FC Dallas take a 2-1 lead into the halftime break, but a controversial second half PK from Pedro Morales earned a point for the Whitecaps.

This match will be remembered, however, for some heroics from goalkeeper Raul “Superman” Fernandez. The Peruvian made seven acrobatic saves denying Morales who had an incredible 12 shots on goal.

Oscar Pareja’s side extended the Whitecaps hoodoo in Frisco as two goals from Blas Perez sent Vancouver’s all-time record at Toyota Stadium to 0-5-0 with a 2-1 win for FCD.

Perez’s first goal was a spectacular, if perhaps accidental, effort from nearly the corner flag. His cross/shot looped over the head of goalkeeper David Ousted and straight into the goal sending the Budweiser Beer Garden into raptures.

Perez won it late for FC Dallas, hammering home a rebound in the 78th minute to earn all three points for FC Dallas, a huge home win that proved vital later in the season.

The Whitecaps earned their second-ever win over FC Dallas with a comprehensive 2-0 home win earlier this month. A five-minute double from Sebastian Fernandez in the first half was all the offense Vancouver needed as the Whitecaps were able to sit on the 2-0 lead for pretty much the entire match.

Despite having 24 crosses to Vancouver’s 5 and earning more shots, corners and possession, FCD was unable to seriously test Ousted in goal in this match.

A hard-fought match that saw 31 fouls committed, coaches from both sides were seen getting into a bit of a tiff at the final whistle adding a little extra spice to what should be an incredible match on Wednesday night at Toyota Stadium.

After the two midweek Knockout Round matches it goes straight into the Conference Semifinals this weekend. Check out the Western Conference Playoff schedule below or see the complete Playoff schedule on MLSsoccer.com.
